As previously described, because ASCT and TACTP is integrated in eNB+, therefore, they directly terminate With the transport layer protocol (TCP/UDP) of UE side, transmission control protocol layer and nothing therefore can be done directly The layer-span combined optimization of line Access Layer, without center YUNSHEN with.It addition, the pressure that TACTP is had The function of data between contracting and caching high in the clouds, UE side and corresponding cloud service entity, it is not required that center cloud Participate in, and independently completed by TACTP.And implement effective QoS guarantee, channel information source combined coding Deng, then by the application programming interface that above-mentioned wireless network is relevant, center cloud and eNB+ jointly complete.

UE in the network architecture that the present invention propose how access to wireless communication network is further illustrated below And use MBB (Mobile Broadband, mobile broadband) business and terminal cloud business.At UE When the area of coverage of eNB+, by existing radio open access procedure, the wireless network of UE and eNB+ Network functional entity sets up one or more wireless network between (including Access Layer and Non-Access Stratum function) Bearer path, thus the application layer of UE and upper-layer functionality entity (the application server cloud tenant of eNB+ ASCT and terminal applies cloud tenant act on behalf of TACTP) between set up IP transmission channel.Wherein, exist During setting up wireless network bearer path between the radio network functions entity of UE and eNB+, eNB+ Radio network functions cloud tenant's WNFCT functional entity by cloud computing mode, from center, cloud obtains nothing The control service that line network function is relevant, as the inquiry of user contracting data, subscription authentication, to wireless network The policy control of network bearer path, charging etc..

When the application layer of UE runs common MBB business, the Client of the mobile broadband application of UE side The transport layer (TCP/UDP) of end, terminates in the ASCT functional entity in eNB+, and ASCT then uses The mode of cloud computing, the high in the clouds of the application server by being integrated in eNB+, by data center by void Intend the forms such as server and application server functionality of the prior art is provided.So, from UE, existing The application server in technology is had to be in eNB+.As it was previously stated, the third party being positioned at data center should With being responsible for passing to the information such as type of service, QoS the application programming interface that wireless network is relevant, eNB+ In ASCT functional entity then obtain the information that these application are relevant, the nothing in eNB+ by Z2 interface Line network functional entity then by the internal interface with ASCT, obtains the information that described application is relevant, from And provide effective QoS guarantee to business.Simultaneously as ASCT has terminated, UE side shifting broadband should With the transport layer protocol of Client end, and can obtain in real time by the radio network functions entity from eNB+ Wireless link and status information (coded modulation information, the wireless channel such as wireless link of Radio Resource Condition, load condition etc. of eating dishes without rice or wine).Therefore, eNB+ can implement transmission control protocol layer and wireless access The layer-span combined optimization of layer, makes full use of Radio Resource, maximum system throughput.It addition, ASCT The radio network functions entity from eNB+ can also be utilized to obtain real-time wireless link and Radio Resource Status information, and it is delivered to, by Z2 interface, the application programming interface that the wireless network of data center is correlated with, Thus the information being correlated with from the wireless network that eNB+ obtains to third-party application APP offer, such as radio chains The instantaneous SINR in road, code modulation mode, wireless channel conditions (average path loss, average SINR etc.), Eat dishes without rice or wine the information such as load condition, consequently facilitating third-party application APP utilizes this bottom-up information to carry out cross-layer Optimize, as carried out channel information source combined coding, i.e. to comprising the business of the media such as video, image, implement The combined coding of channel information source, i.e. according to real-time wireless link status information (such as signal and interference/noise Power is than SINR), based on the principle that throughput of system is maximum and guarantee Consumer's Experience is constant, Combination selection The coded system of the media such as the video of optimum, image and code rate, the channel coding method of wireless link With modulation system etc..

When UE directly obtains cloud service by forms such as SaaS, PaaS, it is integrated in the TACTP of eNB+ Play the function of proxy server, including transport layer protocol (TCP/UDP), the pressure in termination high in the clouds, UE side Data between contracting and caching high in the clouds, UE side and corresponding cloud service entity.Wherein, terminate high in the clouds, UE side Transport layer protocol (TCP/UDP) makes eNB+ can implement transport layer (TCP/UDP) to connect with wireless Enter the layer-span combined optimization of layer, make full use of Radio Resource, maximum system throughput.Converge/compression/ Data between caching high in the clouds, UE side and corresponding cloud service entity can reduce high in the clouds, UE side and take with corresponding cloud Data transfer delay between entity and data transfer rate, accelerate the system response speed to high in the clouds, UE side, Thus improve user and obtain the experience of the services such as SaaS or PaaS.

Third-party application 52 and terminal cloud application 53 can be operate in operator provide data center and Application on corresponding software platform (such as, the platform cloud shown in Fig. 5), it is also possible to be from other Application in the data center of operator and corresponding software platform, or the number of some large-scale IT companies According to the application on center and corresponding software platform, to this end, can be real by the Y1 interface shown in Fig. 5 Interconnection between existing dissimilar cloud.
